Abstract
A self-sealing balloon comprising a tubular balloon neck segment extending from an opening of a balloon gas retaining expansion cavity. A bead of moldable adhesive material is applied in a ring about an interior circumference of a neck portion of the balloon forming a dispensed adhesive roll. The dispensed adhesive roll is at least partially encapsulated within an adhesive staging segment. The adhesive staging segment can be encased within a rolled lip bead by any suitable process. The rolling process aids in forming the ring-shaped adhesive. In use, the balloon would be inflated. The lip bead would be unrolled, exposing the adhesive ring. The moldable adhesive would be compressed forming a seal, entrapping pressurized air within the balloon gas retaining expansion cavity. This provides a low cost, simple self-sealing solution for a balloon.

For purposes of description herein, the terms upper, lower, left, rear, right, front, vertical, horizontal, and derivatives thereof shall relate to the invention as oriented in
(43) One or more balloons 200 are formed using a quick seal balloon fabrication form 100 as illustrated in
(44) Each balloon form member 120 is shaped to include a balloon body mold segment 130 extending from a balloon neck mold segment 140. The balloon body mold segment 130 can be shaped in any desired shape, wherein the shape of the balloon body mold segment 130 defines the shape of the finished balloon gas retaining expansion cavity 210. The balloon neck mold segment 140 is preferably shaped having a circular cross sectional shape to form a circular, tubular balloon neck segment 220. An adhesive dispensing segment 150 is provided in a central region of the balloon neck mold segment 140 as illustrated in
(45) The adhesive roll 170 is formed as a moldable adhesive ring having a moldable adhesive cross sectioned profile formed into a ring or annular shape. The fabrication process positions the moldable adhesive ring 170 to circumscribe an interior circumference of a portion of a length of an interior of the tubular balloon neck segment 220. An adhesive staging segment 172 will be formed from the tubular balloon neck segment 220, wherein the adhesive staging segment 172 will at least partially cover a peripheral surface of the moldable adhesive cross sectioned profile 180.
(46) It is understood that the adhesive roll 170 can be applied using other application methods, including rolling, forming, and the like. The dispensed adhesive roll 170 can be fabricated of any suitable material, wherein one exemplary material is a high tack pressure sensitive adhesive solder under a Product Number 3794 offered by 3M and a second exemplary material is a reusable putty sold under a brand name of DAP BLUESTIK offered by DAP Products incorporated.
(47) The dispensed adhesive roll 170 can be fabricated of a thermoplastic general purpose, high tack, pressure sensitive adhesive that can be spray or bead applied. The chemical base is a block co-polymer. The adhesive material preferably conforms to ASTM D 4236. The composition of the adhesive material can include a rubber-based vehicle.
(48) Although the exemplary embodiment presents an adhesive dispensing segment 150 having a recess formed about a circumference of the balloon neck mold segment 140, it is understood that the adhesive dispensing segment 150 can comprise the plurality of adhesive dispensing apertures 160 in fluid communication with the adhesive primary delivery conduit 162 via a series of adhesive distribution delivery conduits 164, exclusive of the recess formed by the base adhesive control surface 152 and angled adhesive control surface 154.
(49) The exemplary quick seal balloon fabrication form 100 includes a fabrication manifold 110. The fabrication manifold 110 would include a series of fluid conduits (not shown) forming a manifold for transferring an adhesive material from an adhesive material reservoir (not shown) to each of the individual form transition member 114 via any transfer mechanism. The transfer mechanism can be a pump, a pressurized system, and the like. A series of individual form transition member 114 (or similar feature) can be integrated into the fabrication manifold 110 or assembled to a fabrication manifold form surface 112 of the fabrication manifold 110, wherein each balloon form member 120 is attached to the fabrication manifold 110 via the individual form transition member 114. The individual form transition member 114 can provide fluid communication between the manifold of the fabrication manifold 110 and each respective adhesive primary delivery conduit 162. This configuration provides a single passageway for conveyance and disbursement of the adhesive material between the adhesive material reservoir and each of the adhesive dispensing segments 150.
(50) The quick seal balloon fabrication form 100 is transferred placing the multiple balloon form members 120 attached thereto into a vat containing liquid balloon forming material. The liquid balloon forming material coats the balloon body mold segment 130 and balloon neck mold segment 140 of each of the balloon form members 120. The illustration shows two (2) of the four (4) balloon form members 120 being coated with liquid balloon forming material to present a before and after state. It is noted that the liquid balloon forming material is applied to the balloon form member 120, where the liquid balloon forming material covers the adhesive dispensing segment 150. A balloon unfinished edge 222 is created at the terminal end of the self sealing balloon 200.
(51) A volume of adhesive material is dispensed through the manifold, where the material is separated into each of the adhesive primary delivery conduit 162. The adhesive material continues through the adhesive primary delivery conduit 162, where it is disbursed into each of the adhesive distribution delivery conduits 164 and dispensed through the plurality of adhesive dispensing apertures 160. In a first embodiment, the adhesive material is dispensed prior to coating the balloon form member 120 with the balloon material as illustrated in
(52) The self sealing balloon 200 is subjected to a continuous flow of steps to form an adhesive staging segment 172 partially or completely encapsulating the dispensed adhesive roll 170 presented in the exemplary embodiments illustrated in
(53) Initially, the rollers 190 apply a frictional force to the exterior surface of the tubular balloon neck segment 220, causing the adhesive staging segment 172 to extend and begin rolling downward, towards the balloon gas retaining expansion cavity 210 as illustrated in
(54) The adhesive staging segment 172 can be defined as having two segments: an unfinished edge adhesive staging segment 182 and an expansion cavity adhesive staging segment 184. The unfinished edge adhesive staging segment 182 can be defined as a portion of the adhesive staging segment 172 extending from a midline of the dispensed adhesive roll 170 towards the balloon unfinished edge 222. The expansion cavity adhesive staging segment 184 can be defined as a portion of the adhesive staging segment 172 extending from a midline of the dispensed adhesive roll 170 towards the balloon body segment 210.
(55) Although the balloon neck mold segment 140 is illustrated having parallel sides, the balloon neck mold segment 140 can have a taper, where the diameter or circumference proximate the fabrication manifold 110 is smaller than the diameter or circumference proximate the balloon body mold segment 130. The tapered configuration can aid in forming the adhesive staging segment 172.
(56) The balloon unfinished edge 222 can be finished either prior to forming the adhesive staging segment 172, parallel to forming the adhesive staging segment 172, or subsequent to forming the adhesive staging segment 172. The balloon unfinished edge 222 is finished by rolling the free end of the tubular balloon neck segment 220 using at least one lip bead roller 192. The one or more lip bead rollers 192 are positioned about a circumference of the tubular balloon neck segment 220. The lip bead roller 192 frictionally engages with the interior surface 212 of the tubular balloon neck segment 220 causing the free end of the tubular balloon neck segment 220 to roll outward forming a lip bead 224.
(57) Once completed, the self sealing balloon 200 is removed from the balloon form member 120 using any common balloon fabrication separation procedure.
(58) In use, the self sealing balloon 200 is inflated by inserting pressurized inflating gas 230 into the balloon gas retaining expansion cavity 210, as illustrated in
(59) Any individual can deflate the self sealing balloon 200 by pulling the adhesive staging segment 172 open; separating the blob of adhesive material to form a venting passageway. The entrapped air 232 would be released through the venting passageway, deflating the balloon gas retaining expansion cavity 210. The deflated self sealing balloon 200 can be re-inflated and resealed if desired. It is noted that the re-inflation process can require additional finesse, as the dispensed adhesive roll 170 is no longer entrapped within the adhesive staging segment 172.
(60) The self sealing balloon 200 can be fabricated in accordance with a variety of processes, including a first exemplary self-sealing balloon fabrication flow diagram 300 presented in
(61) The first exemplary self-sealing balloon fabrication flow diagram 300 and second exemplary self-sealing balloon fabrication flow diagram 301 differ wherein in the first exemplary self-sealing balloon fabrication flow diagram 300, the step of dispensing the adhesive material upon the adhesive dispensing segment 150 (block 312) is accomplished prior to the step of applying the balloon material onto the balloon form member 120 (block 314) and in the second exemplary self-sealing balloon fabrication flow diagram 301, the step of dispensing the adhesive material upon the adhesive dispensing segment 150 (block 312) is accomplished subsequent to the step of applying the balloon material onto the balloon form member 120 (block 314) and preferably after the balloon material is at least partially cured (block 316). In the second exemplary self-sealing balloon fabrication flow diagram 301, the balloon material can act as the optional, removable form.
(62) The dispensed adhesive roll 170 is encased within an adhesive staging segment 172 by at least one adhesive staging segment roller 190 (blocks 318 through 324). The encasing process initiates by activating the at least one adhesive staging segment roller 190 (block 318). The at least one adhesive staging segment roller 190 frictionally engages with the exterior surface of the tubular balloon neck segment 220 to begin stretching the material to form the adhesive staging segment 172 (block 320). The at least one adhesive staging segment roller 190 continues to draw the section of the tubular balloon neck segment 220, where the interior surface of the tubular balloon neck segment 220 grips the dispensed adhesive roll 170 and draws the dispensed adhesive roll 170 into the adhesive staging segment 172 (block 322). The forming process continues until the adhesive staging segment 172 is formed into the desired shape, finalizing the formation of the adhesive staging segment 172 (block 324).
(63) At any suitable point during the process, at least one lip bead roller 192 is activated and proceeds in forming a lip bead 224 at the balloon unfinished edge 222 of the tubular balloon neck segment 220 (block 330). It is understood that any known process can be utilized to form the lip bead 224.
(64) If the balloon material is not yet cured, the process finalizes the curing of the balloon material (block 326). The self sealing balloon 200 is removed from the balloon form member 120 using any suitable separation process (block 328). At any suitable point in the process, an image can be applied to an exterior surface of the self sealing balloon 200. This image can be printed thereon, sprayed thereon, and the like. The self sealing balloon 200 can be fabricated of a single colored balloon material, a balloon material comprising a swirl of multiple colors, dipped at different levels into different vats of balloon material, each vat comprising a different balloon material color, and the like to create unique balloons 200. The self sealing balloon 200 may be tested to ensure against defects prior to packaging and shipping to a distributor, retailer, and the like, thus terminating the process (block 340).
(65) The self sealing balloon 200 can be inflated in accordance with a variety of processes, with an exemplary self-sealing balloon inflation flow diagram 400 being presented in
(66) The previously described balloon forming processes utilize a custom balloon form member 120 to fabricate the self sealing balloon 200. A self-sealing balloon 600, as illustrated in
(67) Each balloon form member 120 requires a custom design, wherein the design is directed towards a fabrication of the self sealing balloon 200 by including the adhesive dispensing segment 150. A first variant is presented in
(68) In practice, balloon forming material, such as latex, in liquid form, is applied to an exterior surface of the balloon form member 720 and the adhesive adapter exterior surface 756 as illustrated in
(69) The balloon fabrication process can be modified to introduce a powder applying subassembly 780 for application of a surface protecting powder 790 onto the applied moldable adhesive composition 771, as illustrated in
(70) Upon completion of the application of the surface protecting powder 790, the process would continue rolling the lip bead 624, entrapping the power coated applied moldable adhesive composition 771 therein as illustrated in
(71) Another variant of an adhesive applicator is an adhesive dispensing adapter 950, which is illustrated in
(72) In use, a pressure would be applied to the adhesive storage volumetric space 962. The pressure into the adhesive storage volumetric space 962 can be provided by a flow of moldable adhesive composition 970, airflow, a piston, or any other suitable pressure forming source. In the exemplary embodiment, the moldable adhesive composition 970 is supplied to the adhesive storage volumetric space 962 through a propellant/adhesive supply conduit passageway 968 of a propellant/adhesive supply conduit 966. A supply line orifice 963 is formed through the frustum shaped adapter body top panel 953, providing fluid communication between the propellant/adhesive supply conduit passageway 968 and the adhesive storage volumetric space 962. The sourced moldable adhesive composition 970 provides the volume of material and the associated pressure for dispensing the moldable adhesive composition 970 to form the applied moldable adhesive composition 971. The formation of the applied moldable adhesive composition 971 would be controlled by the volume supplied through the propellant/adhesive supply conduit 966 and the time duration of the distribution (application of pressure). The process can optionally include the powder applying subassembly 780 for application of the surface protecting powder 790. Upon completion of the dispensing and formation of the applied moldable adhesive composition 771, the process would continue rolling the lip bead 624, entrapping the applied moldable adhesive composition 971 therein as illustrated in
(73) The self sealing balloon 600 can be fabricated in accordance with a variety of processes, including a third exemplary self-sealing balloon fabrication flow diagram 1000 presented in

The sealing adhesive 1390 is delivered to an adhesive dispenser 1382 by an adhesive supply conduit 1384. The delivery system can also provide sufficient pressure to dispense the adhesive 1390 onto a target surface, such as an interior surface of the balloon neck. An adhesive dispensing orifice 1386 is formed through adhesive dispenser 1382, wherein the adhesive dispensing orifice 1386 is designed to transfer the adhesive 1390 from the adhesive dispenser 1382 to the target surface. The adhesive dispensing orifice 1386 can include a single orifice or dispensing passage (as shown) or a series of dispensing passages. The adhesive dispenser 1382 can be formed to include a nozzle shape leading to the adhesive dispensing orifice 1386. The exemplary adhesive dispenser assembly 1380 includes an adhesive dispenser assembly 1380 that is preferably positionably adjustable to stage to and retract from a dispensing position. The movements of the adhesive dispenser assembly 1380 can be accomplished by employing any of a variety of manual and/or automated movement mechanisms. The adhesive dispenser assembly 1380 can employ a pressure system, a screw drive system, a piston drive system or any other suitable mechanism for dispensing the adhesive 1390 from the adhesive dispenser assembly 1380.
(81) The sealing adhesive applicator assembly 1300 is designed to aid in an application of a bead of adhesive 1390 onto an interior surface 1426 of a balloon neck 1420 of a prefabricated self-sealing balloon 1400. The prefabricated self-sealing balloon 1400 is similar to the self-sealing balloon 200, 600. The self-sealing balloon 1400 is similar to the self sealing balloons 200, 600 with like elements of the self-sealing balloon 1400 being numbered in a similar manner as the self-sealing balloon 200, 600, with a prefix of the numeral 14.
(82) An exemplary method for applying the adhesive 1390 onto the prefabricated self-sealing balloon 1400 is outlined in a fourth exemplary self-sealing balloon fabrication flow diagram 1500 presented in
(83) The fourth exemplary self-sealing balloon fabrication flow diagram 1500 initiates at a start step (block 1402). A sealing adhesive applicator assembly 1300 is obtained in accordance with an obtain adhesive applicator form step 1502. The sealing adhesive applicator assembly 1300 can be assembled to or integrated with an automated device for automating the adhesive application process. During the same acquisition step, a plurality of prefabricated self-sealing balloons 1400 would be supplied for receiving of the adhesive 1390.
(84) The prefabricated self-sealing balloon 1400 would be mounted onto the sealing adhesive applicator balloon neck support element 1310. The balloon neck support element, frustum shaped lead-in segment 1312 is designed to aid in the process of mounting the tubular balloon neck segment 1420 of the prefabricated self-sealing balloon 1400 onto the sealing adhesive applicator balloon neck support element 1310. The free end of the balloon neck support element, frustum shaped lead-in segment 1312 is preferably of a size and shape that is proximate to the size and shape of the opening of the tubular balloon neck segment 1420 of the prefabricated self-sealing balloon 1400, thus easing or simplifying the mounting process by avoiding or minimizing any initial stretching of the tubular balloon neck segment 1420 process. The free, rolled end of the tubular balloon neck segment 1420 is placed upon the balloon neck support element, frustum shaped lead-in segment 1312, as shown in
(85) A lip bead 1424 is formed at a free end of the tubular balloon neck segment 1420. The lip bead 1424 is partially unrolled rearward, from the free end of the sealing adhesive applicator balloon neck support element 1310, mounting the tubular balloon neck segment 1420 onto the balloon neck support element, frustum shaped lead-in segment 1312 and continuing along the balloon neck support element, distal parallel shaped segment 1314 of the sealing adhesive applicator balloon neck support element 1310, as referenced by an unrolling neck upward motion 1370 illustrated in
(86) The adhesive dispenser assembly 1380 is moved into a staging or application position as shown in
(87) Once the dispensed adhesive 1391 is applied and inspected, the adhesive dispenser 1382 is retracted into a stored position, as referenced by an applicator retraction motion 1374, and illustrated in
(88) In an alternate configuration, the adhesive dispenser assembly 1380 can be integrated into the adhesive applicator balloon neck sleeve element 1350. When using this configuration, the adhesive applicator balloon neck sleeve element 1350 would be slideably positioned into a location to dispense the adhesive 1390, forming the dispensed adhesive 1391 on the lip bead adhesive receiving surface 1426 of the tubular balloon neck segment 1420. The process would then continue by dispensing the adhesive 1390, forming the dispensed adhesive 1391 on the lip bead adhesive receiving surface 1426 of the tubular balloon neck segment 1420. The balloon neck sleeve element, interior cavity opening span 1359 would be designed to accommodate the largest dispensed adhesive span 1399 of an acceptable dispensed volume of adhesive 1390.
(89) The adhesive applicator balloon neck sleeve element 1350 is slid forward, towards the free end of the sealing adhesive applicator balloon neck support element 1310 (step 1520). The opening at the free end of the balloon neck sleeve element, frustum shaped lead-in segment 1352 is designed having a balloon neck sleeve element, interior cavity opening span 1359. The balloon neck sleeve element, frustum shaped lead-in segment 1352 would be located at a working end of a balloon neck sleeve element, distal parallel shaped segment 1354. The applied dispensed adhesive 1391 has a dispensed adhesive span 1399. The balloon neck sleeve element, interior cavity opening span 1359 is greater than the dispensed adhesive span 1399, enabling the adhesive applicator balloon neck sleeve element 1350 to pass over the dispensed adhesive 1391 without contacting with the dispensed adhesive 1391.
(90) The dispensed adhesive 1391 is preferably applied proximate the return curve formed in the tubular balloon neck segment 1420, the return curve being located proximate the balloon neck support element, proximal segment indicator 1317. The free end of the balloon neck sleeve element, frustum shaped lead-in segment 1352 would be positioned proximate the balloon neck support element, distal segment indicator 1315, as illustrated in
(91) The adhesive applicator balloon neck sleeve element 1350 is drawn rearward, away from the free end of the sealing adhesive applicator balloon neck support element 1310, as referenced by an initial sleeve retraction motion 1377 (step 1524), which draws the lip bead adhesive covering neck segment 1428 rearward. When the curve defining the lip bead adhesive covering neck segment 1428 approached the dispensed adhesive 1391, an encasing formation balloon neck retention force 1378 is applied to the region proximate the dispensed adhesive 1391, as illustrated in
(92) A number of variants of apparatuses and method of applying a sealing adhesive to an interior surface of a self-sealing balloon were described above. Several optional features can be included in the adhesive dispenser assemblies. The optional features are introduced in the exemplary illustration presented in
(93) The adhesive dispenser assembly 1680 would operate in the same manner as the adhesive dispenser assembly 1380. Like elements of the adhesive dispenser assembly 1680 and the adhesive dispenser assembly 1380 are numbered the same, except being preceded by the numeral 16. In the exemplary illustrated implementation, a balloon sealing adhesive applicator assembly 1600 is representative of any suitable sealing adhesive applicator assembly described herein.
(94) In the balloon sealing adhesive applicator assembly 1600, the adhesive supply conduit 1684 is additionally employed to support the adhesive dispenser 1682. The exemplary adhesive dispenser 1382 includes an adhesive dispensing orifice 1386 having a single passageway. The adhesive dispenser 1682 includes a plurality of dispensing passageways 1686. The sealing adhesive 1690 would be applied to a balloon form neck adhesive receiving element 1650 assembled to a balloon form neck segment 1640, forming a dispensed sealing adhesive 1691. One or both of the balloon form neck segment 1640 and/or the adhesive dispenser assembly 1680 would rotate 1688 about a balloon form neck segment rotational axis 1649 during the application process, forming a circumferentially covering dispensed sealing adhesive 1691. The plurality of dispensing passageways 1686 can provide a more consistent application of the sealing adhesive 1690, forming a broader and consistent dispensed sealing adhesive 1691. The dispensed sealing adhesive 1691 would have a substantially consistent depth (or radial thickness) across a wider axial distance. The balloon form neck adhesive receiving element 1650 would have a surface fabricated of a material that aids in a transfer of the dispensed sealing adhesive 1691 from the balloon form neck adhesive receiving element 1650 to the surface of the neck of the balloon. The exemplary balloon form neck adhesive receiving element 1650 is shown to be proud of the surface of the balloon form neck segment 1640. It is understood that the balloon form neck adhesive receiving element 1650 can be proud of the surface of the balloon form neck segment 1640, co-planar with the surface of the balloon form neck segment 1640, recessed within the surface of the balloon form neck segment 1640, or any combination thereof. The exposed annular surface of the balloon form neck adhesive receiving element 1650 can be planar, as shown, convex, concave, or any combination thereof. Although the dispensing formation of the adhesive dispenser 1682 includes one or more passageways 1686, the dispensing formation of the 1682 can employ any of a variety of dispensing configurations, including a brush, a roller, one or more dispensing needles, or any other suitable dispensing configuration. The dispensing configuration can apply a dispensed sealing adhesive 1691 having a smooth exterior surface, a textured exterior surface, a planar exterior surface, a concave exterior surface, a convex exterior surface, a non-porous or gas free interior volume, a porous interior volume, and the like, or any combination thereof. The adhesive dispenser assembly 1680 can have multiple dispensing subassemblies integrated therewith, enabling dispensing of different materials or compositions to form the dispensed sealing adhesive 1691. This can include a configuration for dispensing a two or multiple part mixture simultaneously or sequentially to form the dispensed sealing adhesive 1691. Similarly, the configuration can be used to inject a gas into the dispensed sealing adhesive 1691.
(95) The sealing adhesive applicator assembly 1300 is illustrated as an independent assembly. A plurality of sealing adhesive applicator assemblies 1300 can be integrated into a single assembly, such as a balloon sealing adhesive applicator assembly 1700, illustrated in
(96) The above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the invention. Many variations, combinations, modifications or equivalents may be substituted for elements thereof without departing from the scope of the invention.
